I also submitted this list to exiftool but the "NX" was apparently left out of the names which I don't completely agree with (https://rt.cpan.org/Public/Bug/Display.html?id=79395). There were Samsung branded Pentax DSLR lenses in the past (D-Xenon). These are lenses for the NX system so why leave the NX out? On the other hand, from what I can see in the sources, neither exiv2 nor exiftool handle the old Samsung DSLR system (which was a clone of Pentax) separately.

I think that the exiv2 and exiftool lens databases should be kept in sync for things like Lensfun to work properly and that the Lensfun database should be updated according to the exiv2/exiftool names. I also looked at the Lensfun database recently and I think I saw only two lenses (30mm pancake and 20-50mm zoom). I have a NX10 and a 30mm plus the kit 18-55mm zoom for which I'd like to make a profile as soon as I have some spare time.

I also had an idea if we could identify the iFn versions somehow. The info might be in comparing firmware versions of non iFn and newer iFn lenses. If nothing else, we can see the firmware version in EXIF which identifies the lens. I'm not sure if such information is realy important... Maybe it is even possible to hack an iFn firmware to work with a older non iFn lens, but that's another discussion.

Samsung is planning new lenses for the NX but nothing has come out yet. Let's see what this year's Photokina will bring.

I'd be happy to maintain the Samsung NX lenses database if there isn't someone doing it already.

Difficult question... Samsung announced more lenses in the past, some of which got cancelled later on. There are unreleased lenses and the 45mm prime that isn't available yet. It seems the 12-24mm was just ready sooner than lenses with IDs 10 and 11;-)
